I use to love microcenter, but now, I don't know, its ok if microcenter only focus on PC's and please do so if thats the case. BUT they also have isles of cables and adapters and what not. Everytime I go there, they don't have it, and the answer is always..."I never seen something like that, and if it exist, it probably cost alot". SOOOOOOO I guess you guys don't have it? All I am asking for a USB3 extension cord and yet, that was the answer I got. I ultimately had to order from Amazon. Micro Center has become another Best Buy where they go...."ooh yeah, thats a online only item, want use to order it for you?"
